Application 'lledy June 18.

To .all whom. it may concern.'

lie it known that l, DAVID 0. MARSHALL, a citizen of the United States, residing,t at tit. Louis, tlvlissouri7 have invented a certain new and usefulv Improvement in Heelfirooving Machines`l of-which the following is a full` clear, and exact description, such as will enable others skilled in the art to which it appertains to malte and use the same. i

This invention relates to a machine for forming a groove or recess in a shoe heel at the junction of the breast and bottom end face of the heel so as to improve lthe appearance of the heel.

@ne object of my invention is to provide a machine of the general character referred to which is so constructed that it can be op erated successfully at a high speed by an unskilled workman.

Another object is to provide a machine ot the character referred to that can be adjusted easily tc adapt it to heels of various sizes and styles and to vary the depth and .length of the groove or recess formed in the heel.

Fig-ure l of the drawings is an end eleva.- /tional View of a machine constructed in aceordance with my invention.

Figure 2 is a detail view, showing a heel arranged in engagement with. the cutter of the machine.

Figure 7 is a perspective view of a. heel that has been grooved by mynimproved 4ina-- 4chine.

Referring tothe drawings which illustrate the preferred form of my invention, LA designates a rotary cutter, preferably' a tapered cutter provided with ylongitudinallyn i disposed teethyB designates a horizontal shaft/,to which said` cutter is fastened, C

designates a belt for driving said shaft and D designates the frame of the machine.

lhe machine 1s equipped with a movable -heel carrier E which is so constructed that a heel can be placed in same and said carrier thereafter moved towards the cutter" A .so as to cause said cutter to form a recess or groove a; in the heel at the junction of the breast g/ and the bottom end face a of the heel., as shown. in Fifrures 2 and 7. The carrier E is so constructed that only a few seconds are required to place the heel in the carrier, move the heel into engagement with the cutter and then remove the heel from the carrier. li/lloreover7 the carrier is so con structed and arranged that no skill on the part of the operator is required inthe 0peration of manipulating the carrier during the operation of grooving the heel.

ln the form of my invention herein illustrated the carrier E is oscillatingly mounted on the frame D of the machine at one side of the cutter A and is adapted to he moved from the position shown in full lines in Figure l. into the position shown in dotted lines in said figure to bring the heel into engagement with the cutter. At the completionpf the grooving operation tf carrier is trestored to the position shown in full lines in Figure 1 and the grooved heel in the carrier is removed and replaced by an ungrooved heel. The particular con struction of the carrier E is immaterial so far as my broad idea is concerned, so long as it is of such design that the heel can be arranged .in operative position in same quickly, will he held securely in the carrier durinnr the grooving operation and can he removed from the carrier quickly at the com pletion of the groei/ing* operation. 'One convenient way of constructing the carrier is to provide it with a socket piece 1 upon `which the heel can be laid sidewise with its longitudinal anis extending lengthwise of the cutter A and its breast 1,1 presented toai-ds said cutter, a stop 2 being arranged at the right hand sido of said socket piece so as to 'form an abutment for the upper end face zu of the heel and'amother. stop 3 being arranged in front of said socket piece so as to form an abutment for the breast g/ of the' heel: 1H .U10-@fA FSPSGS l form the socket,

- approximately to the shape of one-half of the heel and mount said socket piece on the carrier in such a Way that it can be removed easily and replaced by another socket piece when the style 'or size of the heel to be giooved in the machine is changed. In the machine herein shown the carrier E is provided with a base portion to which the socket piece 1 is firmly clamped hy a bolt or other suitable fastening device 4 that passes through an open-ended slot in the socket piece, and said base portion is provided at its'right hand edge with an upwardly-projecting flange that constitutes the stop 2 previously referred to.

. The carrier E is preferably secured to the upper end of a rock arm F that is oscillatingly mounted on a horizontally-disposed support G which projects forwardly from the front side of the trame of the machine, and said frame is equipped with stops 5 and 6 that co-operate with the rock arm F to limit the movement of the carrier E relatively to the cutter A, the stop 6 being preferably adjustablv mounted, as shown in Figure l, so that it can be-Set in Idifferent. positions to control the depth of the groove formed in the heel by the cutter A.

In order that the machine may be used for grooving heels otvarious styles and sizes means is provided for enabling the carrier E to be adjusted aiigularly relatively to the cutter A, raised and lowered relatively to said `cutter and also adjusted longitudinally.

of the axis of the cutter. In the form of .my invention herein illustrated the support G on Which the rock arm F is mounted is rigidly connected to a vertically#adjustable plate 7' whose lower end rests upon an ad- )usting screw 8 that is adapted to be mani pulated so as to raise and lower the platel and thus change the level of the carrier relatively to the cutter. After the plate 7 has been set in the proper position it is clamped securely to the frame D of the machine b v clamping bolts 9 on said plate that pass through vertically-disposed slots in cross pieces at the vfront end of the frame. as

shown in Figure 1. This adjustment of the carrier `is used to center the heel properly with vrelation to the cutter, and thus cause the cutter to form a symmetrical groove or recess inthe breast of the heel. In order that theshape or form of the groove m in the heel' may be varied without changing the `cutter A or substituting a cutter of different form, the carrier E is mounted on the rock ann F in such a way that it can be turned into the position shown in dotted lines in Figure 5, so as to arrange the heel `on the carrier atan angle to the axis of the cutter.

ne convenient Way of accomplishing this istdprovidethe base portion of the carrier with a rigid, depending rod 10 that is screwed into an internally-screw-threaded bore in the rock arm F, a lock nut 1l lieing provided for holding the carrier in ad justed Aposition.V In the event the vertical adjustment of the plate 7 which carries the roel: arm F is not sufficient to bring tho longitudinal axis ot the lice] iii lioi'i:c:,iiilul alignment with the longitudinal axis o lv` the cutter A, the lock nut 11 can be loosened.

adjustment of the carrier without disturl'` ing the position of the vertically-adjustable plate 7 on the `frame o1 themaehine.

Wlhen the machine is 'tolbe lused for gioov ing a relatively high French heel, it is necessary to adjust the carrier E longitudinally otl the axis ot' the cutter A fromthe position shown in full lines in Figure 6 into the position shown in dotted lines'in said ligure. In the form rof. my invention herein illus trated this is accomplished by providing ilu rock arm F with iin internally sci-civ threaded sleeve 12 ivhose threads co-opcrate vwith screw threads 13 on the horizontally-- disposed su )port G to move the rock arm F longitudine ly of said support when said sleeve 12 is rotated. As shown in Figure I, the sleeve 1Q is retained in adjusted position oii-the support G by a lock nut 14, and the rock arm F is provided at its lower end with a horizontallydisposed, tubular portion 15 that is free to oscilliitc on the sleeve l2. p lVhile l have hei-cin illustrated my invention embodied in a machine in which the. portion of the machine that carries the heel 'is adapted to be moved relatively to the cutter to bring the heel. into and out of eiigagenient. with the cutter, and is so constructed that it can be adjusted into various iositions lo j adapt the machine to heels ot di eient styles and sizes and to vary the shape und depth ot the groove formed in the heel. I do not wish it to be understood that niv broad idea is limited to a machine of this particular construction, as my invention, broadly stated, consists of u machine composed of a cutter and' a heel carrier arranged iii such a Way that one ot said elements can be moved relatively to the other to cause the cutter. to form a lgroove or'iezess iii the heel at the junction of the breast and bottom end face ot the heel und so constructed and combined that oniot said elements can be adjusted relatively to the other vertically,

lllll singularly and in a direction lengthwise of the longitudinal axis of the cutter.
